IMPROVEMENT IN HAME-FASTENINGS.

Specification forming part of Letters Patent No. 218,599, dated August12, 1879 application filed July 8, 1879.

To all whom it may concern.-

Be it known that I, JAMES LOUIS TILLY, of Shreveport, in the parish ofOaddo and State of Louisiana, have invented a new and useful Improvementin Hame-Fastenings, of which the following is a specification.

The invention consists in a self-fastening hooked slide and slottedhooked strap, made, preferably, of malleable iron.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is a vertical longitudinal section, andFig. 2 is a plan view, of the slide and strap. Fig. 3 is a detailed viewof the eccentric G.

A is the strap, having slots D D D, &e., and provided with book E.

B is the slide, having hook E, and provided on the inside with abearing, b, and eccentric O. G is an eccentric, and is provided on theunder side with a small projection or catch, H, and also with handle 0.It turns upon the pivot P; but the strain is taken by the hearing 1),the pivot P merelyserving the purpose of a turning-point.

In using this fastening, the strap A is inserted in the opening I), andis then pushed in the required distance, when the catch H drops intooneof the slots D, and the fastening is complete.

It will be noticed that the slide B is in the form of a closed box, openat both ends, and having the eccentricO inclosed therein. This eccentricis, more properly speaking, a pawl or catch, having the pivot P passingloosely through it, or through an enlarged orifice; and theinner end ofthe pawl or catch is made eccentric, so that when turned downward oroutward, to allow the projection H to enter one of the slots D in thestrap A, the eccentric end of the pawl will bind tightly against thebearing 1) in the box or slide and take off all the strain from thepivot. At the same time, by this peculiar construction, the greater thestrain is on the fastening the tighter it will hold.

I construct the fastening of metal. I prefer malleable cast-iron.

The hooks E E receive the eyes or rings on the lower ends of the hames;then, by pushing the strap A into the opening b of the slide B thedesired distance, the catch H on the eccentric 0 drops automaticallyiHlIL one of the slots 1), and makes the fastening of the hamescomplete.

Simply lifting the eccentric O by its handle 0 allows the strap A to bewithdrawn and the hames to be unfastened.

I am aware that a hame-fastener has been made consisting of a bar havingcertain grooves, opening, and ears, with a tongue pivotedbetween theears for securing a slotted bar, and I do not claim such as myinvention.

What I claim as my invention is- In a hamefastening, the combination,with the slotted bar A, the box or slide B, formed with the interiorbearing, b, and the pawl or catch 0, loosely pivoted in the box, andhaving its inner end made eccentric to bind against the bearing b,substantially as and for the purposes herein set forth.
